共享主机中的symfony项目出现一些错误

Question

I'm a beginner in Symfony. I build a very simple project using Symfony that works correctly work in localhost. I upload all content of project folder expect 'web' in the root of my shared hosting and upload 'web' folder to 'public_html' folder. Import MySQL to my created database in host correctly and change 'parameters.yml' and change database connection details. Change chmod of '/var/logs/' and '/var/cache' to 777. But when going to website get an internal error.

Errors detail :

What is the problem? Please help me. Thanks

Answer 1

You probably didn't clear the cache.

Try to clear the cache by running command:

php bin/console cache:clear --env=prod

Or if you use dev-environment (it is not right for production server) you shoud use:

php bin/console cache:clear

If you have no access to shell you can clear the cache manually by removing whole folder with the name of your environment from var/cache . For prod environment you should remove var/cache/prod folder.

Answer 2

you need to add rwx permission to the webserver user that is www-data on the session directory through act package if you don't have it install by

$ sudo apt-get install acl

if you do have it just type

$ sudo setfacl -R -m u:www-data:rX project-symfony/var/sessions
$ sudo setfacl -dR -m u:www-data:rX project-symfony/var/sessions

the second line is to give permissions rwx to files under that dir Best practices are to give rx permission to the project itself rwx to var/cache var/logs and var/sessions , rwx to its derivate (respectively as i did above ).

after that you need to clear cache [delete the --env=prod if you are in development mode] and you're good to go !

php bin/console cache:clear --env=prod
